I just developed this idea to use for an invoicing system at our satellite offices. Quite often my users want to add charges or make changes to charges that cause the sort order of their invoices to go out of whack. The predefined sort orders don't help them, because they may need to reorder charges based on random criteria or how a particular client requests to see their invoices. So it's not as easy as giving them the option of selecting different sort fields. I read on this forum that permanently resorting a file or select group of records involves exporting and re-importing the data. I didn't like the idea of involving an extra file or dealing with serial number issues, so I designed this technique. Enjoy.

I've modified the attachment to include the options of using a portal instead of list view and whether or not to allow modifier keys.

Modified attachment for Mac users. I used to program for Mac, but never x-plat, so I didn't know about the 'store compatible graphics' option. Sorry, guys!
